To all whom it may concern.-

Be it known that I, ALEXANDER STANLEY ELMORE, a citizen of England, residing at Spring Grove, I-Iunslet, Leeds, in the county 5 of York, England, have invented certain new and useful Improvements in Apparatus for the Manufacture of Metallic Articles by Electrolysis, (for which I have obtained Letters Patent in Great Britain, dated September 16,

1890, No. 14,624; in France, dated July 4, 1891,

No. 214,641; in Austria-Hungary, dated J anuary 31, 1892, No. 51,818, and No. 83,592; in Belgium, dated July 4, 1891, No. 95,573; in Spain, dated August 28, 1891, No. 12,303; in Norway, dated July 13, 1891, No. 2,416; in Switzerland, dated July 8, 1891, No. 3,803; in Italy, dated July 27, 1891, No. 75, Vol. LIX; in Victoria, dated August 14, 1891, No. 8,959; in New South Wales, dated August 17, 1891, No. 3,196; in South Australia, dated August 17, 1891, No. 2,014; in New Zealand, dated August 24, 1891,No. 5,153; in Western Australia, dated March 8, 1892, No. 324; in Queensland, dated August 17, 1891, No. 1,825; in India, dated October 26, 1891, No. 238; in Luxemburg, dated July 14, 1891, No. 1,473; in Canada, dated November 14, 1891, No. 37,787, and partly in Great Britain by patent dated August 15, 1888, No. 11,778,) of which the fol- 0 lowing is a full, clear, and exact specification.

My invention relates to the manufacture by electrolysis of metallic articles, such as tubes, cylinders, or other pieces of circular section, also of sheets, strips, rods, or other 3 5 pieces obtained by cutting cylindrical shells electrolytically deposited. The depositing, as is well known, is effected in an electrolytic bath on a revolving core or mandrel, the deposited metal being rendered strong and compact by the action of a burnisher on it as it is deposited. These burnishers, which are moved to and fro along the revolving metal, become worn, so that the area of their pressing-surface becomes gradually enlarged and less effective for burnishing. Sometimes in order to distribute the wear the burnishers are made as rollers retarded, so as to revolve more slowly than the metal surface on which they act; but these are not well adapted for uneven or corrugated surfaces. Now according to my present invention, I make the burnisher in the form of a wheel mounted to revolve on an axis perpendicular, or nearly so, to a plane passing through the axis of the revolving mandrel, and I cause this wheel to travel to and fro along the metal surface and at the same time to rotate, so as to present always a free acting-surface. TVhen the surface of the deposited metal is uneven or corrugated, the burnishing-wheel is made of radius less than the least radius of any of the hollows of the surface, and is thus capable of entering into and acting in all the hollows.

In the drawings, Figure 1 is a transverse section through an electrolytic bath, showing the application according to my invention of a wheel-burnisher to a revolving cathodemandrel; and Figs. 2 and 3 are respectivelv a transverse section and a longitudinal section of a modified arrangement.

In the drawings the letter M indicates a mandrel, which in practice is revolved in the direction of the arrow thereupon.

The letter A indicates an arm, which is caused by suitable gearing to travel to and fro parallel to the axis of the mandrel and carrying the burnisher along the surface of the metal deposited on the mandrel. In any part of a slot formed in this arm I fix by setting-screws a bracket B and a rod R, which can slide in a socket S, pivoted on the bracket B. This rod R is forked at its lower end, and in the fork is mounted the wheel V7, of agate or other suitable material, presenting its edge to one periphery of the mandrel, against which it is pressed by the strain of a caoutchouc band C, which is passed round the rod R and engaged in one or other of a set of notches formed in the bracket B. As the arm A moves longitudinally to and fro the wheel W rolls alongthe mandrel, presenting always a fresh portion of its edge to effect the burnishing. When the one edge is worn, the wheel my be turned round on the axis B, so as to bring the other edge into use. In order to insure the rotation of the burnishingwheel W, either at the rate due to its rolling,

or, if desired, at greater or less speed, l'adopt 1: the arrangement shown in the part transextends along the bath andjstightened by a; weight X or otherwise. The pulley P in traveling along um wire or (acid is caused to revolliieigiviing rotation to the tutti-suing wheel W, which may be made to revolve more quickly or more slowlyth'a'nfthe speed'diie to its rolling by making the pulley P of less or greater diameter. v

Having thus described the nature of my in- 'Ve'ntion and the best means I know for carr ing the same into practical "efiect, I claim deposited by electrolysis on a mandrel, the combination, with a tank and a mandrel a1 ranged to revolve therein, of a traveling arm and 'a buriiishe'r-rollersupported by said'a'r'm In this case I fiX on the axis of the 1.' In an apparatus, for bui'nishihgthe inetal and revolving on an axis lying in aplane perpendicular to the axis of the mandrel.

2. In an apparatus forburnishing the metal deposited by electrolysis on a mandrel, the combination, with a tank and a mandrel arranged Qto revolve thiereimof a traveling arm, and a burnisher-roller pivotally supported by said arm and revolving on an aids lying in 3 plane perpendicular to the aiis of the man- 3. Inan apparatus for burnishing metal deposited by electrolysis on a mandrel, the combi-nation, with a taukand a mandrel arranged to revolve therein, of a traveling arm, a bracket secured to said arm and provided with a pivoted seek-e a burhisher-roller carried by said socket, and means for'holdin g the bui'iiisher-wheel against the m andi'fel.

Iii testimoiiy w ll or I have signed my name to th'isspe'cifi at, ii l th presence of two subscribing witnesses, this 9th day of July, 1891.
